original application filed October-17, 1913, Serial No. "395,651 5. Divided and this application filed June :33,

0 all whom it may concern:

Be it known that l, CLAUS Hrnnrcn; Ker-in, a citizen of the German Empire, and residing at Leipzig, Germany, have invented certain new and useful Improvements in Motor-Flows, of 'which the following is a specification. 4

This invention relates to motor plows of the type described in my copending patent application Serial No. 795,695, filed October 17, 1913, from which this application has been divided out;

In motor plows of the type in question raising of-earth by the anchors .is avoided as much as possible by inserting the anchors straight into and removing the same straight from the ground.

A primary object of this invention is to protect the driving chains as much as pos' sible from any soil which is nevertheless carried up by the anchors and falls oil therefrom when they move with the upper'side ot' the chain.

According to my invention the anchors are made of an improved shape such that any earth which falls oil the flukes when the anchors are moving with the upper side of the chain falls outside the one or more chains. 1 also provide improved guards for the one or more chains.

To these ends the invention consists in the construction, arrangement and combina' and pointed out in the claims.

Several embodiments of the invention are diagrammatically represented by way of example in the accompanying drawings, wherein Figure 1 is a section showing the guards or covers for the chain when the anchors are forked and their heads are driyen with only one chain, and Fig. 2 is a like view showing a spade'shaped anchor to be driven by two driving chains, and guards for the latter; Fig. 3 is a like view showing another form of a forked anchor to single chain, and a guard for, the latter; Fig. d is a like view showing another form of a forked anchor driven by a single chain, and a modified guard for the latter, and Fig. 5 is a like view showing a second form of a spade-shaped anchor driven by two chains, and a modified guard for the latter;

Fig. 6 shows an improved form of a coverbe driven by a serial No. saw n5.

mg oand 0:. bolt comprising a number of overlapping, relatively displaceable parts tor equalizing the varying distance apart of the anchors, and Figs. 7 and 8 are elevations showing in two different positions of the anchor, the arrangement of a guard for collecting any earth which may fall oil the anchor when it is directed vertically upward, while when the anchor is directed downward the soil can fall oii' the guard on to the ground.

Referring firstly to Figs. l to 5, the chains are'so arranged that they are located completely outside the range of soil falling from the dukes.

In the embodiment shown in Fig. l. tile numeral 20 designates the sprocke'lf-wheol which rotates about a fixedly mounted ivot 26 and drives by means oi the chain. the head of the anchor havingthe rollers 18 which run in the guides 17. T he anchor 9 itself is fork-shaped, and its tlukes 27, 2/? are so far apart that they enter into the ground outside the planes containing the chain 21 and the rollers 18. ln addition, side pieces or flanges 22 prevent any earth thrown oil laterally from the takes 2'7, 2? entering into the guide-ways 17.

in the embodiment shown in Fig. F2, in stead of a forked anchor i: provide an anchor having an ordinary spadeshapcd links 9, but the driving chains 21 driven by sprocketwheels 20 are disposed laterally outside the reach of soil thrown vertically up down by the fluke 9. The anchor has lateral heads 28 by means of which it carried by the rollers 18. -HQI6 agai the flanges or side pieces 22 prevent any dirt thrown. 0 later ally from the ilulres entering into the guides or chains.

In contradistinction to Fig. 1, in the embodiment according to 3 the flakes 2f, 2'! of the anchor project laterally out ()1 and completely covering the chains and guide-ways, and, in addition lateral. washers or disks 29 mounted. on the anchors or on the pins of the chain protect the guide-ways from dirt which is thrown laterally oil the llukes. I

in. the illustrative embodiment according to Fig. l, instead of the washers or disks 29 (Fig. 3) for protecting the guideaways Patented when, rain."

theltorm shown in c the guide-ways and embrace the plates 22 connected to the guidewaya its I the flukes 27, 27 of the anchor have a U- out of slots in the guide way. The lateral slots may be protected from dirt thrown off laterally from the anchors by washers or disks29 mounted on the pins 34: or on the pins of the chains.

In the illustrative embodiment according to Fig. 6 the protection from dirt is affor'ded by a rotating band which consists, however, not of one uniform piece of material, but of several overlapping parts 35, 35 which are provided with holes 36 and slots so that theparts 35, 35 can shift relatively to one another, but the band nevertheless always affords proper protection.

Lastly, Figs. 7 and 8 show another kind of protection for the guide-ways and chains, each anchor 9. being provided with a guard or shield 37 fixed to it in such manner that when the anchor is directed vertically ward any dirt carried by it falls onto the shield or guard and is thrown off when the anchoris directed downward.

I claim 1. In a car for driving a plow, the combination of a plurality of flaked anchors; means for guiding the same and inserting ried by spade-shaped and pro-. ,vided with lateral arms 33 carried by the pins 34 projecting into and withdrawing them from the soil; and a pair of relatively shiftable bands having holes and slots therein, each anchor fluke penetrating through a hole of one band and a corresponding slot of the other.

2. In a car for driving a plow, the com bination of endless guide-ways, anchors, rollers on the anchors guided in the guideways, an endless chain for driving ehors, each anchor being forlcshaped and having its flukes located outside the vertical plane containing said chain, and guards carsaid rollers.

3. In a car for. driving a plow, the combination of endless guide-ways, anchors, rollers on the anchors guided in the guideways, an endless chain for driving the an-.

the anthe guide-ways for said chain and I chors, each anchor being fork-shaped, havto ing a U-bend in each limb and having its flukes located outside the vertical plane containing said chain, and guards for said chain and said rollers extending into the ld ben'ds.

4. In a car for driving a plow; the combination of endless guide-ways, anchors, rollers on the anchors guided in the guideways, an endless chain for driving the anchors, each anchor being fork-shaped, having a. U-bend in each limb and having its flukes located outside the vertical plane containing said chain, and guards for said chain and said rollers extending into the U-bends, the ends of the guards in the U-bends being formed as brushes.

In testimony whereof, I aliix my signature in the presence of two witnesses.
